SPECIFICATION forming part of Iietters I atent No. 543,109, dated July23, 1895.

Application filed Marchfi, 1895. deriallflo. 540,791. (No model.) e

To aZZ whom it may concern.-

Be it known that I, Soorr STEWAR'na citizen of the United States ofAmerica, residing at Rivesville, in the county of Marion and Stateof.WestVirginia,haveinvented certain new and useful Improvements inCopy-Hold ers, of which the following is a specification,

' reference being had therein to the accompanying drawings.

[O The object of this invention is the production of a copy'holderparticularly adapted for use by amanuenses in connection with typewriting machines; and it consists in novel means for automatically andsimultaneously 1 5 releasing the clutches that'elevate and hold thecarriage that it may fall by gravity to itslowermost position forfurther manipulation. Vith the above and other objects invievi theinvention consists in the various novel details ofconstruction,arrangement, and com bination of partsto be hereinaftermore fully set forth and specifically claimed.

In describing theinvention in detail reference ishad to the accompanyingdrawings,

forming part of this specification, wherein like characters denotecorresponding parts in the severals views, in which-- Figure 1 is a viewin perspective of my im- 3 5 In the drawings, 1 denotes the base; 2, an

extension at right angles to the base.

3 3 are vertical guides extending from the base and provided with ways4, in which the extensions of the rod 5 of the carriage are adapted toride, said extensions acting also as a spring to lessen the jar andstrain when the carriage falls. v A brace 6 is secured to the base andguides and a buffer 7 is secured to the base to re- 5 ceive the impactof the rod 5, these latter being details of construction which do notenter into the invention, but are added to increase the eff ciency ofthe device.

Secured to the top of the guides isa bridgepiece 8 withforwardly-extending arms 9,

.which receive the ends of a pivoted frame 10 carrying a guide 11'adapted to bear against the copy and indicate the proper matter to becopied.

The copy-holding clamp consists of a frame 12 pivoted to the loops 13,the spring M serving to hold the section 15, which passes in front ofthe carriage, pressed against the surface of the copy.

Arranged on the bridge-piece is a springclutch formed in duplicatesections 16 with slots in the free ends to receive the rod 5, whichpasses throu'gh the said bridge-piece. The sections of this clutch arereduced centrally to provide for increased elasticity, and

one section is provided with a pin or stud 17, -which passes through thebridge and is engaged by a shoulder or trip on the movableGIHtChyWh-(dl'GbY the stationary clutch is elevated' and its holdreleased.

The movable clutch consists of a base 18 having upturned ends 19centrally recessed to receive the upwardly-extending ends 20 ofthe'sections of the clutch, which are adapted to strike against theunder side of the bridgepiece and be pressed down, thereby elevating theopposite ends out of engagement with the rod 5 and releasing the bitethereon. The clutch is formed ofduplicate members 21 with semicircularrecesses in the ends to embrace the rod 5. In Fig. 1 one member of theclutch is provided with an aperture 22 to allow the pin or stud to passthrough and abut the base of the clutch. The spring 23 holds the membersof the clutch in theirpositions, but can be dispensed with, as the baseis so formed as to hold the members of the clutch for all ordinaryusage.

The movable clutch is mounted on a rod 23 connected with a crank-lever24 which extends inwardly to the center from the handoperated lever 25.The rod 23 is held normally depressed by theaction of the spring 26secured to the brace 6 and to the red, as shown. 9 5

The operating-lever 25 is pivoted to a log 2 7'and is.provided with anelongated'aperture 28, in which the end of the crank-lever 24 operates.

" A gage to restrict the movement of the op- IOO eratinglever and thethrow of the clutch is provided, consisting of a screw-threaded stud 29having a cap 30 which can be elevated or lowered to limit the motion ofthe lever, as will be apparent.

In the modification shown in Fig. 4 the collar A abuts the pin, whilethe construction of the clutch and the arrangement of the spring isslightly alteredthat is, the spring B is wound around the rod 5 and isengaged by the collars A and Z), the collar 1) being pressed by the arms21, which are pivoted to a casing b In order to release the carriage andallow the same to drop the lever is moved transversely, the action ofthe spring 31 secured to the end of the crank-lever being overcome. lhelever is then depressed so as not to come into contact with the gage 30,and when so depressed the movable clutch is elevated until the curvedextensions come into contact with the bridge and the pin or stud of thestationary clutch is elevated by the baseplate of the movable clutchwhen they simultaneously release their hold and the carriage descendsand the operating-lever automatically returned to its normal position byaction of thesprings 31 and 26, respectively.

By extendingthe frameof the table slightly above the table proper I forma loop 32 through which the sheets may be passed when copied, and it maybe found desirable to employ a spring for retaining the loop in contactwith the sheets, especially when the paper is unusually stiff.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is

1. In a copy holder, the combination with a table, a rod secured theretoand working in an aperture of a clutch base, duplicate clamping membersarranged on the base, and having upwardly curved outer ends to abut atrip, a fixed clutch to hold the table in its advanced position andmeans for elevating the members of the fixed and movable clutches out ofengagement with the rod simultaneously for the purpose described.

2. In a copy holder, the combination with the table having suitablesupports, of a stationary clutch secured on the bridge piece of thesupport, a movable clutch consisting of a base, and duplicate clampingsections with upturned ends adapted to abut the bridge piece, and meansfor elevating the stationary clutches out of contact with the supportingrod at the time the movable clutch releases its hold thereon as and forthe purpose described.

3. In a copy holder, the combination with the table having a rod to beengaged by clutches, of a stationary clutch consisting of two members, aprojection depending from one of said members, a traveling clutchconsisting of duplicate members, the said stationary clutch beingtripped by the movable clutch engaging said projection the movableclutch being simultaneously released by a trip abutting the ends of themembers of the movable clutch, an operating spring pressed lever,a gagefor limiting its movement and means whereby the lever may be moved outof contact with the gage, depressed and automatically returned to itsnormal position, for the purpose described.

4. In a copy holder the combination with a table having suitable clampsand supports, of a traveling clutch formed of duplicate members arrangedon a base and having upturned ends to abut a trip, a fixed clutch, aprojection secured thereto and means whereby the ascent of the movableclutch will engage the projection of the stationary clutch and the endsof the movable clutch willabut atrip to release both automatically asand for the purpose described.

In testimony whereof I aiiix my signature in presence of two witnesses.
